| Abstract: | Solution properties of the piezoelectric crystal are studied by using a transistorized oscillator. At the definite temperature, the crystal ceases to oscillate. Grounding the detection cell can improve the oscillation performances of the crystal and lower the cease-to-oscillate temperature. And the effects of grounding the detection cell on the cease-to-oscillate temperature and the frequency are found to be in linear relation with the electrolyte concentration. |
